Lime mortar is considerably more ‘green’ than OPC – nearly 97% less CO2 emissions.

Lime mortar is a much better product for restoring older buildings as it has good porosity properties allowing it to breath. This is an important property for single skin exterior walls. The only draw back of lime mortar for some other applications is the lack of hardness.

OPC is much harder than lime mortar but has virtually no porosity. OPC can be used on double skin walls. The problem with OPC is the amount of CO2 emissions associated with it and the hardness can cause stone / brick to chip at the corners. It is a poor product for single skin walls as it will retain damp inside the building and is not compatable with restoring old, lime based buildings.

Ecolime, has created a unique lime based product, Formulated Hydraulic Cement (FHC), that has very low CO2 emissions and can be made to any grade. Similar to lime mortar with high porosity and low hardness or as hard as any OPC mortar with low porosity. In all cases the CO2 emissions of FHC are very low, making it the perfect OPC replacement product for those builders who are concerned about global warming or are involved in ecological builds.
